A Chilly Passage                                       -      N      - 
(-------------------------------------------------)     - <---(M)---> E
                                                        -      -      -

The air still has an icy bite to it, but at least you are on solid
footing again.  The lichen again covers the walls rather thoroughly, as if
to make up for the fact that it was unable to grow just east of here due to
the ice.  The floor is bare stone, with a few small rocks strewn about. 
Occasionally, you hear the sound of animals moving about.  The passage runs
to the east and north.
